Update GPG Publickey In repomap

Purpose

Currently the Public_Key value of the repo map is being populated with a GPG publickey that contains \n instead of 0 bytes. The \n. characters are being rendered on the Ironbank Frontend. We should update the Public_Key content to no longer delimit newlines using \n

Plan

Inspect the publish stage of the pipeline to see where we're inserting the newline characters and remedy.
